For some months, my garage door opener has started to acting more and more weird. It randomly forgets the calibration for how heavy the door is to open and close, it totally stops responding, or there are random delays from a command is send until it actually starts moving. So as I see it, it is only a matter of […]

It has been a while since my last post, but I haven’t really done any new things, and everything has pretty much just worked as it should. What broke, was my very first Sonoff, which is in the most read post (http://captain-slow.dk/2016/05/22/replacing-the-itead-sonoff-firmware/), and has been put through quite a few experiments and mishaps, one which involved 5v where it should […]

The last few weeks I have been working on different projects for industrial robots, and while working on that I came across some genuine power supplies, and then decided to test the efficiency between the genuine and copy. To test that I use two mains power meters, and use the average between the two (I don’t have a high end […]

After getting the lamp to work correctly, I wanted to take it a step further, and put my own code on it. What I can see through the matte cover, this seems to be a bit more difficult. But let’s take a look inside and see if we can’t find them anyways.

In my latest box from ITEAD, I had both a Sonoff 4CH, and one of their led lamps. And in this post I will start by just using the lamp as they intended it to, by controlling it from the eWeLink app. When I first powered it on, it quickly flashed the led’s on and off, and they seems to be […]

So far flashing the ESP8266 has been pretty easy, but with the new Smart Home devices from itead,it has become a bit more complicated. The reason for this, is because they have changed from the ESP8266, to the physically smaller ESP8285. The function of the 8285 is the same as the 8266, but it got the memory build in, instead […]

For more speed, I have made some changes, so the site is now running on a newer version of PHP. It is hosted on SSD disks, got more memory available, got an ssl certificate, and I also enabled a cache plugin, which I should have done long ago. If you run into problems, please let me know. Everything should be […]

Some time ago Seeed Studio reached out to me, and offered me a set of pcb’s of my own design, so I could review their pcb service. And here we are, after Chinese new year, and our postal service probably delivering my package in my neighbors mailbox, I finally got them. 🙂 The PCB design I decided on trying, was […]

One month ago I wrote about the Sonoff SC from ITEAD, after having used it for a month, do I think it is any good? Placement I have tried to have it a few places, to test how the readouts from it would be, here it is in the window at my dining room. Here I tested the light sensor […]
